How do you determine where to place the decimal point in a problem that involves multiplication of decimals
Count the total number of decimal places in the num-bers that are being multiplied. This is the number of decimal places that should be in the product before any zeros are dropped. For example, when a number with one decimal place is multiplied by a number with two decimal places, the product should have three decimal places.
The slanted line between the x and the 3 in the equation x/3 =6 means that x is ___________ by 3
